But our man Damon who tested the Hellcat said that he had way more fun in the V6 Challenger than the Hellcat on track, because the Hellcat was nearly unusable. On the street, lower power, like the 1.0 liter Fiesta, lets you ring it out without actually breaking any laws at all. Because it isn't fast enough to break any laws. Can you imagine a Fiesta 1.0 with the suspension, appearance, and character of the Fiesta ST? Call it something like the Fiesta ST Jr. and you'd have a winner on your hands.
